Henk's Hollow Locality (Miocene to of Australia)

Also known as HH site, Riversleigh

Where: Queensland, Australia (19.1° S, 138.7° E: paleocoordinates 28.0° S, 135.9° E)

• coordinate based on nearby landmark

• small collection-level geographic resolution

When: Faunal Zone C zone, Langhian to Langhian (16.0 - 11.6 Ma)

• Hand et al. (1993) state that the fossils have been collected from an "as yet unnamed freshwater limestone" which is situated near the top of Archer's (1989, 1991) "System C sequence".

•The suboptimal stratigraphic nomenclature of Archer is replaced by a concept of faunal zones by Arena (2004, PhD thesis, Uviv. New South Wales, Sydney), confirmed by Travouillon et al. (2006, Alcheringia, 30, Suppl. 1, 323-349). Faunal Zones A, B, C are identical to "Systems" A, B, C of Archer.

•Faunal Zone C is Middle Miocene in age.

• group of beds-level stratigraphic resolution

Environment/lithology: terrestrial; gray, white limestone

• Fossiliferous rocks of the Riversleigh area are said to represent freshwater carbonates whose depositional history appears to involve a complex sequence of fluvial and karst processes (Archer et al., 2006, Alcheringia, 30, Suppl. 1, 1-17 and references cited therein).
• "dirty white to grey limestone" (Smith & Plane, 1985)

Size classes: macrofossils, mesofossils

Reposited in the UQ

Collection methods: bulk, acetic
